12(6) + 14 ⋅ 2 ⋅ 2 =

Answers

Answer 1

Answer: 128

Step-by-step explanation:

12(6)+ 14x2x2

Use PEMDAS

1.Do the parentheses-(These are parentheses) first

When the number it touching another number like this, you need to multiply them together

12x6=72

72+14x2x2

2. Then do exponents, but we don't have any so next to multiplying

2x2=4

72+14x4

14x4=56

3. Now we divide, but we don't have to divide anything so now we add

72+56=128

4. There is no subtraction in the problem, so now we are done and the total is 128

Have a good day =)

I dont need an answer I just need help.. The picture below, is it just 9x9 and like 6x6 or is it 9x2 and 6x2? And then the answer would be c x 2 or c x c?

Answers

Answer: 45

Step-by-step explanation:

Pythagorean Theorem is a^2+b^2=c^2
In this case it would be 9^2-6^2 which is 45

Answer:

In this case, it would be 9x9 and 6x6

Step-by-step explanation:

The ² in the problem means to multiply the number by itself, like 9x9. It's called the square.

a² + b² = c²

eg.

(a x a) + (b x b) must be = (c x c)

c = hypotenuse which means it is the longest part, which is why it is a² + b² = c²

The equation shown describes a relationship between x and y.
y = 5x + 2
If the value of x increases by 1, what is the corresponding increase in the value of y?

Answers

y should increase by five every time

5x is just a multiple 5 but without knowing how many tines your multiplying. Now we know that x increases by 1 each time, so it should just be normal multiplying. 5(1) = 5, 5(2) = 10, 5(3) = 15 and so on. It's a constant increase of 5.

y is gonna increase by 5 every time so it’s 5(2), 5(3), 5(4) and so on

-4y = 72

Horozontal or vertical??

Answers

Vertical is the answer

Answer:

horizontal

Step-by-step explanation:

You want to know if the equation -4y = 72 describes a horizontal or vertical line.

Constant equation

The equation reduces to ...

-4y = 72

y = -18 . . . . . . . . divide both sides by -4

The points on a graph that have y-coordinate -18 will form a horizontal line. They are all 18 units below the x-axis. The line is parallel to the x-axis.

Additional comment

The equation x = constant describes a vertical line.

If you are in doubt, you can always graph the equation with your graphing calculator.

Firstly, you have to find the area of the whole shape. After that, you subtract that from the area of the individual triangle to get your answer.

The whole shape is a rectangle, with a length of 6 and a width of 7.
To find the area, multiply 6 by 7=42yd^2

The area of the entire shape is 42yd^2

Now, the vertical 4yd side plus the height of the dotted triangle will equal 6yd.
So the height of the dotted triangle is 6-4=2yd.

The horizontal 4yd side plus the base of the dotted triangle will equal 7yd.
So the base of the dotted triangle is 7-4=3yd.

Formula for area of triangle: 1/2 x base x height
1/2 x 4 x 3= 6yd^2

The area of the dotted triangle is 6yd^2

Now subtract the area of the whole shape by the area of the dotted triangle to get the shaded region.

42-6= 36yd^2

Area of shaded region: 36yd^2 (i think)

Joseph has a fair dice with 4 faces numbered 1 to 4.
He also has a fair dice with 6 faces numbered 1 to 6.
He rolls both dice.
Find the probability of rolling a different number on each dice.

Answers

Answer:

To find the probability of rolling a different number on each dice, we can determine the total number of possible outcomes and the favorable outcomes.

The total number of possible outcomes when rolling a 4-sided die and a 6-sided die is the product of the number of sides on each die: 4 × 6 = 24.

The favorable outcomes occur when we roll a different number on each die. We can calculate this by considering all the possible combinations.

For the first die (4-sided), there are 4 possible outcomes.

For the second die (6-sided), there are 6 possible outcomes.

Since we want different numbers on each die, the total number of favorable outcomes is 4 × 6 = 24.

Therefore, the probability of rolling a different number on each die is:

Probability = (Number of favorable outcomes) / (Number of total outcomes)

Probability = 24 / 24

Probability = 1

Hence, the probability is 1 or 100%.

Elena has a budget of $50 for a new watch. she finds two watches that are $8 above and $8 below her budget, respectively.

Part A

0=|x+___|+___

Part B
What are the prices of the watchee Elena finds?
$______and$______

Answers

X+8 & X-8

The first watch is 58 and the other watch is 42

The requreid, The absolute value equation to represent this situation is 0 = |x - 50| + 8 and Elena finds a watch that costs $50. The other two watches are priced at $42 and $58.

What are functions?

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Part A:

Let x be the price of the first watch she finds. Then the price of the second watch is x - 16 (since it is $8 below her budget).

The absolute value equation to represent this situation is:

0 = |x - 50| + 8

Part B:

To solve the absolute value equation, we need to consider two cases:

Case 1: x - 50 is positive

If x - 50 is positive, then we can write the equation as:

0 = x - 50

x = 50

This means that the watch Elena finds costs $50, which is exactly her budget.

Case 2: x - 50 is negative

If x - 50 is negative, then we can write the equation as:

0 = -(x - 50)

0 = -x + 50

x = 50

Again, this means that the watch Elena finds costs $50.

So, Elena finds a watch that costs $50. The other two watches are priced at $42 and $58.

A 25-foot magazine rack begins 20 feet south of the checkout desk and continues south. What are the coordinates of the beginning and end of the magazine rack? Explain or show how you got your answer. ANSWER CORRECTLY WITH AN EXPLANATION

Answers

Answer: The coordinates of the beginning of the magazine rack are (0,-20), and the coordinates of the end of the magazine rack are (0,-45).

Explanation:

The magazine rack begins 20 feet south of the checkout desk, so its starting point is 20 feet below the x-axis. This gives us the coordinates (0,-20) for the beginning of the rack. Since the rack is 25 feet long, it extends 25 feet to the south of its starting point. Therefore, the endpoint of the rack is 20 feet (the starting point) minus 25 feet (the length of the rack), or -5 feet south of the checkout desk. This gives us the coordinates (0,-45) for the end of the rack.

Brainliest?

The given information tells us that the magazine rack begins 20 feet south of the checkout desk and continues south for a length of 25 feet. Since the magazine rack is only moving in the south direction, we can say that the x-coordinate (horizontal distance) of both points will be the same.

Let's assign the x-coordinate of the checkout desk as 0. Then, the x-coordinate of the beginning and end of the magazine rack will also be 0.

The y-coordinate of the beginning of the magazine rack is 20 feet south of the checkout desk, which means it is 20 feet less than the y-coordinate of the checkout desk. If we assume that the y-coordinate of the checkout desk is y = 0, then the y-coordinate of the beginning of the magazine rack is y = -20.

To find the y-coordinate of the end of the magazine rack, we add the length of the rack (25 feet) to the y-coordinate of the beginning of the rack (-20 feet). This gives us y = 5.

Therefore, the coordinates of the beginning of the magazine rack are (0,-20) and the coordinates of the end of the magazine rack are (0,5).

What is 2x+21? Please it's due in about 15 minutes!!!

Answers

Answer:

The value of x is 21

Step-by-step explanation:

2x+21 is a linear equation with one unknown, x. To solve for x, we can use the following steps:

1. Subtract 21 from both sides of the equation. This will isolate x on the left-hand side of the equation.

```

2x+21 - 21 = x

```

2. Divide both sides of the equation by 2. This will divide both sides of the equation by 2, which will cancel out the 2 on the left-hand side of the equation, leaving x by itself.

```

x = (2x+21)/2

```

3. Simplify the right-hand side of the equation.

```

x = x/2 + 21/2

```

4. Combine like terms on the right-hand side of the equation.

```

x = (1/2)x + 21/2

```

5. Subtract (1/2)x from both sides of the equation. This will isolate x on the left-hand side of the equation.

```

x - (1/2)x = (1/2)x + 21/2 - (1/2)x

```

6. Simplify the right-hand side of the equation.

```

(1/2)x = 21/2

```

7. Multiply both sides of the equation by 2. This will multiply both sides of the equation by 2, which will cancel out the (1/2) on the left-hand side of the equation, leaving x by itself.

```

2*(1/2)x = 21/2 * 2

```

8. Simplify the right-hand side of the equation.

```

x = 21

```

Therefore, the value of x is 21.

2x+21
2x+21=0
-21/2
X = -21/2 or -10.5

READ the information about public health and individual freedom - Most people want to be healthy, and most people want as much freedom as possible to do the things they want. Unfortunately, these two desires sometimes conflict. For example, smoking is prohibited from most public places, which restricts the freedom of some individuals for the sake of the health of others. Likewise, car emissions are regulated in many areas in order to reduce pollution and its health risks to others, which in turn restricts some peoples freedom to drive the vehicles they want. In a society that values both health and freedom, how do we best balance the two? How should we think about conflicts between public health and individual freedom?Perspective One - Our society should strive to achieve the greatest good for the greatest number of people. When the freedom of the individual interferes with that principle, freedom must be restricted.Perspective Two - Nothing in society is more valuable than freedom. Perhaps physical health is sometimes improved by restricting freedom, but the cost to the health of our free society is far too great to justify it.Perspective Three - The right to avoid health risks is a freedom, too. When we allow individual behavior to endanger others, weve damaged both freedom and health.WRITE an essay in which you state your own perspective on the issue of Public Health and Individual Freedom, which analyze the relationship between your perspective and at least one other perspective.
